A man running late for his once in a lifetime dream...

A man running late for his once in a lifetime dream job interview is frantically trying to find a parking spot in a packed lot...

Time is not on his side, and he starts to panic. In his last ditch attempt, he turns to the skies, and begs: “God, please, help me out here. I’ll do anything… I’ll quit smoking. I’ll stop drinking. I’ll donate money to charity.” As soon as he finishes his plea, the skies open up, and the bright light shines on to an empty parking space. The man holds up his hand, and goes: “Never mind, I found one”.

Daguerrotype

In 1839, the daguerreotype photo process was announced at the French Academy of Science. Previous photographic processes required hours of exposure, but the daguerrotype (named after its inventor Louis Daguerre) needed only a few seconds. The plate was prepared with a layer of photo-sensitive silver halide, was exposed, developed using mercury vapour, and fixed in a solution of sodium hyposulphite. The image remains delicate, and must be protected under glass against damage by touching. The daguerreotype was produced with a direct positive image, needing no intermediate negative, but thus could not yield multiple reproductions made possible by later photographic processes.«[Image: first daguerrotype portrait in the Library of Congress collection.
